Solar Panels Aren’t Just Shiny Faces

It's Watts Beneath That Make Them Smile!

Many homeowners don’t realize that annual servicing is essential to keep a rooftop solar system operating at peak efficiency. It’s not uncommon for an individual panel to fail, but cleaning or visually inspecting your solar panels rarely reveals hidden faults. A professional solar check-and-test service ensures that your entire system is inspected, tested, and analyzed for any inefficiencies or failures.

Solar is NOT set-and-forget! Even if your system looks fine, hidden faults can go undetected without proper electrical testing. The image above shows our technician servicing a system—he cleaned the panels (no visible issues), visually inspected all components (no obvious faults), but when testing with a meter, it exposed a hidden fault that could have led to total system failure.

Common Issues We Find During a Solar Service:

• Shoddy installations with loose wiring, incorrectly installed cable ties, and poor connections
• Grime-covered panels reducing efficiency
• Birds or rodents nesting under panels, damaging wiring, and interfering with electrical components
• Poor mounting and layout impacting energy production

Comprehensive Solar Testing & Maintenance

Our solar check-and-test program goes beyond just cleaning panels:

• Debris removal from panels and system components
• Corrosion checks on key parts or roof areas affecting performance
• Testing cable insulation, open-circuit voltage, and short-circuit current
• Ensuring proper switchboard labelling, circuit breaker function, and earthing protection
• Recalibration and voltage testing to manufacturer standards

Have You Ever… had your solar system, inverter, and components actually tested and serviced for electrical performance?

Annual servicing is critical to preventing costly failures and inefficiencies. Don’t forget or underestimate the importance—maintaining your system’s lifespan saves you money on lost performance and prevents premature unit replacement!

During your service, we can also advise on system upgrades or ways to maximize energy efficiency. Identify problems before they become expensive failures—Book your solar service today!
